Gus Poyet will appeal against his sacking by Brighton and Hove Albion after finding out about his dismissal while working as a pundit for the BBC. "I think the BBC have a great story forever, because a manager getting information that he is being released from his employment by the BBC is quite surprising," he said.

Poyet has been sacked after an internal disciplinary hearing at Brighton. The Uruguayan, part of the BBC's Confederations Cup team, was informed that his tenure had come to an end only when a member of the broadcaster's production team informed him when on air on Sunday evening.

"The only thing I'm concentrating on is the appeal," he told the BBC. "Because it is the right thing to do. I cannot stand it any more because after all this I took a little bit longer with my lawyers and they are reading the email I still don't have myself and so it's very difficult to make any comments.

"I need to read everything first but I'm saying I will appeal whatever they say in the email – I know myself and I want to make sure everything is clear and whatever step I need to make I will make in the future."

Poyet had also been prohibited from speaking to Brighton's players. "I hope that after reading the statement that I will be able to talk to them," he added. "It's something that's been really sad because they gave me so much, they made me so proud and not being able to answer a phone call, answer a text, or even an email for legal reasons is quite unusual. So I would like now, if I get the permission, for them to hear from me."

Poyet had guided Brighton to the play-offs – in which they lost to Crystal Palace – last season but his tenure became shrouded in doubt, firstly as his assistants Mauricio Taricco and Charlie Oatway were told to stay away from the club. It was subsequently announced that Taricco's ban was lifted but that Poyet was subject to disciplinary action, with that case delayed after the former Chelsea player initially failed to attend due to what were described as "disputed legal reasons".

The precise reason for the hearing has not been explained by Brighton but it is clear the manager had angered club directors in some way. Asked whether he could tell the BBC what had happened he said: "No." On Sunday evening, a Brighton statement said: "Gus Poyet has been informed today by Brighton and Hove Albion football club's internal disciplinary panel that his employment has been terminated with immediate effect. This followed his suspension, an investigation, and a subsequent formal disciplinary process. In line with the club's own procedures, and UK employment law, Mr Poyet now has a right of appeal.

"As such, the club will make no further comment on this matter or recent LMA statements at this time. Given the close proximity of the new season, the club will, in conjunction with its board, now seek to appoint an interim manager pending the outcome of a possible appeal. The interim manager will oversee the initial weeks of pre-season preparation alongside the club's existing staff.

"The club's first-team players report back as planned for pre-season testing on Monday 24 June, with the squad's first technical sessions commencing on Thursday 27 June. The team play Whitehawk on Saturday 6th July and leave for their summer training camp in Spain on 14th July." Poyet had signed a five-year contract at Brighton in September 2011. He was linked with the vacant managerial post at Reading, following the sacking of Brian McDermott.

Brighton's defeat to Crystal Palace was overshadowed by a bizarre incident in which excrement was found in the visitors' dressing room prior to the teams meeting at the Amex Stadium. Poyet was furious at the affair and sent an angry email to club staff, in which he also criticised the issuing to home fans at the match with paper "clappers" in an effort to generate atmosphere.

Brighton are believed to have lined up the former Maccabi Tel Aviv manager Oscar García as Poyet's replacement.
